复制ASM files到文件系统。
分类: ORACLE11G 数据库 124人阅读 评论(0) 收藏 举报

有时有这样一种需求:就是要复制ASM files到文件系统上。

这样就可以利用很多OS命令来对文件进行操作或利用OS命令复制文件了。

下面有三种不同的方法:

一。 利用DBMS_FILE_TRANSFER.COPY_FILE过程

$ rman target /

RMAN> list backup of controlfile
2> ;


List of Backup Sets
===================

$ . oraenv
ORACLE_SID = [+ASM1] ? MCSPSR_1
The Oracle base for ORACLE_HOME=/orahome/oracle/product/11.2.0/dbhome_1 is /orahome/oracle

二。利用RMAN中的convert 命令

Or copy the file with rman convert command.
$ rman target /

三。利用ASMCMD中的cp 命令
$ . oraenv
ORACLE_SID = [grid] ? +ASM1
The Oracle base for ORACLE_HOME=/export/grid/app/11.2.0/grid is /export/grid/app/grid
$ asmcmd
ASMCMD> ls
